Application filed April 7,

This invention relates to improvements in a corrugated container of the type known as a slide and primarily adapted for use in shipping electric batteries having binding posts or terminals for circuit wire connections, which must be protected in the shipping and 7 handling of the goods.

It is our object to reduce the cost of such containers while affording increased protection for the contents and facilitating the assembling of the containers and inspection of the contents. v

More particularly, it is our object to provide a container of the corrugated slide type, formed entirely from two blanks, one being an outer sleeve and'the other the inner, bottom and top portions and also forming a protecting pad for the projecting termmals of the battery.

Other objects will appear and be more fully pointed out in the following specification and claims.

Referring to the drawings, Figure 1 is a perspective view of our improved container in Open position, ready to receive the goods to be shipped; Fig. 2 is a'plan view of the container with a battery in lace therein and with the pad portion folde 11%011 the top of the battery, the cover proper eing'in open position, as for inspection of the contents; Fig. 3 is a vertical section taken on the line 3-3 of Fig. 2 but showing the cover in closed position; Fig. 4 is a similar vertical section through an alternate form of container; Fig. 5 is a detail, perspective view of the exterior slide or sleeve; Fig. 6 is a plan view showing the inner blank of the referred form shown in Figs. 1, 2 and 3; Flg. 7 is a similar plan view of the blank forming the inner member of the alternate form of container and Fig. 8 is a side elevation of the blank shown in Fig. 7, partially folded, as for insertion in the outer sleeve.

Our improved container is constructed en- CORRUGATED-BOARD ooNTArNER.

being corrugated. As best shown in 1-, 2 and 5, we provide an external sleeve 9,

1 formed from a rectangular blank, having its.

.inner surface and creased along lines 12-to form .a bottom 13, rear and front sides 14 and 15 respectively, a cover flap 16, a pendant flange 17 and pad portions 18 and 19 formed integral with the normally upper end of the side 15. The corrugations upon the front and rear sides 14 and 15 extend at right angles to or transverse the corrugations upon the sleeve 9. The cover flange 17 and a portion 20 of the side 15 adjacent to said flange in the assembled and closed container have the corrugations flattened-or crushed so that the combined thicknesses of the portions 17 and 20 are equal to the thickness of the side 15. The battery 21 to be packed in the container is of the rectangular ty e, having plain bottom side and top sur aces and terminals or binding posts 22, which project from the top along one margin, as shown in Fig. 2. The combined thicknesses of the pads 18 and 19 are equal to the height of these terminals 22, so that when the blanks are folded and assembled, as shown in'Fig. 3, the terminals 22 are protected by said pads. 1

To facilitate outward bending along a creased line 12*, we refer to cut the corrugated sheet along said line, as indicated in. Figs. 1 and 6. This permits the flattened portion 20 to be folded outward, substantially. at right angles to the sides 15, when it is desired to insert or remove-the battery from the container Without bodily removing the inner blank 11 from the sleeve.

.TO insert-a battery 21 and assemble the container, the blank 11 may be folded, as indicated in Fig. 3 about the battery and the pads 18 and 19 secured in place upon the top of the battery by applying suita le tape or paperstrips 23 having a coat of-moist adhe sive. With the blank 11 covering the top, rear, bottom and front sides of the battery 21, said blank and battery are inserted in the sleeve 9, the cover flange 17 fitting snugly be tween the outer surface of the portion 20 and inner surface ofthe sleeve 9. The main oover flap 16 is held in closed position above the battery terminals 22 by the flange .17. Now toinspect the battery without removing the strips 23, the. cover flap 16 maybe opened by withdrawing the flange 17 and. exposing the terminals 22, as shown in Fig. 2. v viously, this gives access to the terminals 22 to facilitate testing the voltage while retaining thebattery within the sleeve by means of the pad portions 18 and 19.

In the alternate form of our device, shown in Figs. 4, 7 and 8, the outer sleeve 9 is identical with that described above, but the inner blank 25 has the pad portions 26 and 27 formed integral with the cover,instead of integral with the front side 15, as in the preferred form. The blank shown in Figs. 7

' and 8 is creased to form a front side 28, a

bottom 29, a rear side 30, a cover flapv 31, an integral flange 32, an extension thereof 33, and the pad portions 27 and 26 are integral with the flange extension 33. The flange 32 and its'extension 33 have the corrugations flattened so that their combined thickness is equal to that of the front side 28 or normal thickness of the sheet. As shown in Figs. 4 and 8, the extension 33 is arranged to be folded upon the flange 32, when it is inserted in the slide or sleeve 9. It will be evident that the pad portions 26 and 27 protect the battery terminals 22 in the same manner as the portions 18 and 19 of the lpreferred construction. To gain access to t e terminals 22 of the battery 21, it is only necessary to withdraw the flan e 32 and its extension 33 from the positions own in Fig. t-between the battery and inner surface of thesleeve 9 and to swing the cover 31 to an open position like that shown in Fig. 8.

Obviously, the inner blanks 11 and 25 may be secured in closed position by placing strips of dpaper or tape across the to and bottom an securing the same by a outer surface of the slide member 9. The advantages of our device include reducing the cost of the container and at the same time facilitating inspection of the contents without breaking the securing strips 23 or removing the batte from the container. Heretofore, it has h een common practice to provide detached or separate strips of corrugated board in place of the pads 18, 19, 26 and 27. It will be evident that these loose pads are apt to become lost or are omitted when the battery container is open for inspection and later closed with consequent failure of the .rotection for said terminals in subsequent andling or shipping. Such esive to the whereby the combined thic 2 eena-vs separate pads also increase the cost ,of the containers and the work of assembling the same. Obviously the flattened portions 17 and 20 of the pre erred construction and the portions 32 and 33 in the alternate form p'ermit insertion of these members for retammg the cover in closed position in the space avail-' able between the front of the battery and outer sleeve 9. Thus, the crushed or flattened portionsaflord a snug fitting retaining means,

which abut against the unyieldingouter surface of the batte Having descri ed our invention what we 019.1111 as new and desire to ends, an'inner member creased an folded to form front, rear, bottom and top panels and an integral pad arranged to lie between the inner surface of said top panel and the end of a battery in said container, said pad being arranged to afford a s ace for battery terminals and to support said cover panel in spaced relation to said terminals 2. In a two blank container, formed from corrugated sheet material, a tubular outer member open at its to and bottom ends, an inner member crease and folded to form front, rear, bottom and top panelsand a pad formed inte ral with'said front panel, arranged to lie eneath the inner surface of said top-panel and a pendant flange on the normally free edge of said to panel arranged to be inserted between sai outer and inner members and to overlap said front panel, the overlapping portions ofsaid flange and front panel having a combined thickness substantially equal to the thickness of'the front panel.
